A heatproof mat

A heatproof mat is a piece of apparatus commonly used in tabletop lab experiments that involve moderate temperatures (for example, when a Bunsen burner is being used) to prevent damage to a work surface.[1] They may also be used for domestic equipment, such as hot plates,[2] hair stylers,[3] hair straighteners[4] or other hot objects.

Traditionally, such mats were made of asbestos. Fiberglass, calcium silicate or other substitutes are now used because of the toxicity of asbestos fibres.
